Electric drawer with gesture sensing

Abstract

An electric drawer with gesture sensing includes a cabinet body, a controller, a drawer body, a driving device, and a gesture sensor. The gesture sensor is used for sensing a gesture to open or close the drawer body and for transmitting the corresponding information to the controller. After that, the controller controls the operation of the driving device to open or close the drawer. Through this electric drawer, there is no need for the user to manually push and pull the drawer, and the user can open or close the drawer with a gesture to facilitate the use of the drawer.

What is claimed is: 
     
       1. An electric drawer with gesture sensing, comprising a cabinet body, a controller, a drawer body, a driving device and a gesture sensor; the cabinet body having an accommodating chamber with an opening facing forward; the controller being disposed on the cabinet body; the drawer body being movably disposed in the accommodating chamber; the driving device being disposed in the cabinet body, the driving device being connected with the controller for driving the drawer body to move inwardly and outwardly; the gesture sensor being disposed on the cabinet body and exposed out of the cabinet body, the gesture sensor being connected with the controller;
 wherein two inner side walls of the accommodating chamber are provided with rails extending laterally, two sides of the drawer body are provided with slide rails, and the slide rails are slidably connected to the rails and movable along the rails; 
 wherein bottom portions of front and rear ends of the slide rails are formed with positioning recesses respectively, the cabinet body is provided with a stopper therein, the stopper is connected with the controller, the stopper is located in the opening of the accommodating chamber, the stopper is mated and engaged with one of the positioning recesses, and the stopper is configured to limit the position of inward and outward movement of the drawer body; and 
 wherein the stopper disengages from the positioning recesses in a de-energized condition to allow drawer body to be manually opened or closed in the de-energized condition. 
 
     
     
       2. The electric drawer with gesture sensing as claimed in  claim 1 , wherein the driving device includes a motor, a gear, and a rack; the motor is mounted close to an inner side of the opening of the accommodating chamber through a fixing plate; the gear is mounted on an output shaft of the motor, the motor drives the gear to rotate back and forth; the rack is fixed to a side of the drawer body and extends laterally, and the rack is meshed with the gear. 
     
     
       3. The electric drawer with gesture sensing as claimed in  claim 2 , wherein the motor is provided with a position sensor, and the position sensor is connected with the controller. 
     
     
       4. The electric drawer with gesture sensing as claimed in  claim 1 , wherein the gesture sensor is exposed out of a front side of a top end of the cabinet body.
